AI has raised expectations for speed and visual polish, creating a “fidelity trap” where designers feel pressure to make every artifact look finished even when rougher work would better support the decision at hand. A practical definition of “good enough” starts by identifying what the work needs to unlock—such as a usability test, engineering estimate, design direction, or leadership approval—and applying only enough fidelity to achieve that goal. Clear quality criteria can help teams know both when work isn't ready and when to stop, preserving human judgment as AI compresses more of the design process.
